Abstract (en)
A wet type developing device is provided that allows the regulation of a liquid toner supply by the anilox roller to a surface of a developing roller and the erasure of a history of an electrostatic latent image on the surface of the developing roller to be performed with one dual purpose roller. A wet type developing device 4 including a developing roller 10 and an anilox roller 20, the wet type developing device comprises: a dual purpose roller 30 being opposite to the surface of the anilox roller 20, leaving a gap therebetween, upstream of a region of contact between the surfaces of the anilox roller 20 and the developing roller 10 and being in contact with the surface of the developing roller 10 upstream of the region of contact between the surfaces of the anilox roller 20 and the developing roller 10 and being rotationally driven, wherein a surface part of the dual purpose roller 30 consists of a porous member which has flexibility and elasticity.
